Hi,
if your Technics is direct drive or belt driven with dc motor it should have less audible noise coming from the motor compared to a tt driven with an ac motor. Now if you get a 2 or 3 phase ac motor in a heavy casing you minimize further any noise. If you hear the rotating noise only by a stethoscope on the VPI there is nothing wrong with that.
